Application filed March 11, 1916. Serial No. 83,566.

To all whom it may concern:

Be it known that we, CLARENCE I. flew- KINS and ROBERT W. CAMPBELL, citizens of the United States, residing at Baileyton, in the county of Greene and State of Tennessee, have invented new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to a combined ratchet wrench and drill and has for its object to simplify and improve the existing art by producing a device of this character which embodies few simple interchangeable partsand which will perform its functions with ease, accuracy and surety.

With these objects in view and others which will appear as the nature of the invention is more fully understood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings: Figure 1 is a side elevation of the device, Fig. 2 is a central vertical longitudinal sectional view through the same, Fig. 3 is a transverse sectional view approximately on the line 3-3 of Fig. 1, Fig. 4 is a sectional view approximately on the line 4-4 of Fig. 1, Fig. 5 is a sectional view approximately on the line 5-5 of Fig. 1, Fig. 6 is a perspective view of the stock with the jaws removed therefrom, and Fig. 7 is a similar view of the body or sleeve.

The device includes a stock 2 which is preferably square or rectangular in cross section and which is provided with a centrally disposed longitudinally extending reduced spindle 8 that is for a portion of its length formed with threads 4. The spindle, adjacent the end thereof, is formed with a continuous depression 5 and this end is adapted to receive a sleeve or collar 6 projecting from the head member 7, transverse members, such as screws 8 passing through the sleeve or collar 6 and being received in the depression 5, connecting the head with the spindle end of the stock.

The square or rectangular end of the stock is provided with an opening 9 that communicates with two of its sides and pivotally connected within the said opening, as at 10, is a'pair of jaw members 11 and 12. These jaws are of a similar construction and are adapted to have their inner faces brou ht together, in a manner presently to be de scribed, and each of said aws has its outer edge arranged angularly or disposed outward from its end which is pivoted within the stock, while the opposite end of each of the jaws is formed upon its inner face with a depression whereby the said jaws may engage with a nut or the like. The jaws from the mentioned depression and upon their said outer ends and at the central portion of their inner faces are formed each with a longitudinal depression providing a pocket 18, the said pocket adapted to receive the end of a drill bit or the like so that the device may be employed in connection with such hits as well as being employed as a wrench.

The numeral 1 T designates a sleeve or body, the same having a substantially square or rectangular bore and two of the opposite walls of said bore from the end of the said sleeve are inclined or beveled, as at 15, to contact with the inclined or angular outer faces of the jaws 11 and 12. The sleeve is formed upon what we will term its inner end with a centrally arranged longitudinally ex tending collar 16, and this collar is rectangular or elliptical in cross section. The collar is formed with a bore which communicates with the bore of the sleeve, the said bore being suflicient to snugly receive the spindle end of the stock 2, and the collar is provided with a transverse slot or opening 17 to receive a nut member 18 that engages the threads l of the spindle. Owing to the peculiar formation of the collar 16 it will be noted that two of the opposite sides of the nut project through the slot 17 beyond the sides of said collar, and the nut is preferably formed with a round periphery which is milled to facilitate the operation of the same. By adjusting the nut it will be noted that the sleeve may be moved longitudinally of the stock to permit of the adjustment of the jaws to compensate for the various sizes of articles with which they are adapted to engage or with various sizes of bit heads which are to be arranged in the socket between the jaws. If desired the meeting faces of thejaws may be provided each with a depression providing a pocket for the opposite end convolutions of a helical spring, as shown in the drawings, so that the said jaws will be automatically moved away from each other.

The wall provided between the sleeve 14 and the extension 16 thereof serves as a contact member for the shoulder between the stock and the spindle to limit the movement of the sleeve toward' the outer en'd'of the jaws, and the outer shoulder provided between the said sleeve and its extension or collar 16 is formed with an outwardly extending flange 16' which is provided with spaced notches 19.

The numeral 20 designates a lever which adjacent one of its ends is formed with a round opening which is adapted to receive a round wall 21 provided by the extension 16 at its juncture with the sleeve 14, the said end of the lever resting upon the shoulder 21 of the sleeve 14. V,

The numeral 22 designates a plate which has one of its ends forked and the inneror connecting wall of the fork is rounded to engage with the rounded wall 23 provided upon the outer surface of the sleeve below the notched flange. This plate 22 has one of its ends provided with a right angular extension 24: which is connected to the lever 20. Pivotally secured between the plate-22 and the lever 20 is a pair of oppositely disposed dogs 25 and 26, the said dogs being normally swung upon their pivots to bring their engaging ends toward each other or toward the notched edge of the flange 16 through the medium ofa connecting spring 27; Arranged between the plate 22 and the lever 20 centrally of the dogs 25 and 26 is the bit 28 of a key. member, the spindle of the key being received in suitable journal openings in both the plate and the lever and the handle 29 for the said bit being disposed over the face of the lever 20. By turning the key in one direction one of the pawls 25 will be brought away from the notches 19 of the flange l6 permitting the other pawl 26 to engage with the said notches and when the'lever is actuated the device will be turned in one direction. Likewise when the key is turned to bring its bit into contact with the other pawl 26, the pawl 25 will be brought out of engagement with the notches of the flange and this permits of a reverse turning of the device.

Having thus describedthe invention, what we claim is:

1'. Ina device for the purpose set forth, a stock having oppositely. arrangedjaws pivoted therein and extending through the sides of the stock, the stock having a reduced spindle extension provided with Copies of this patent may be obtained for which is round in plan and threads, a head upon the spindle, a sleeve surrounding the stock and frictionally enduced sides thereof, a nut upon the threads of the spindle and projecting through the opening, a round peripherally notched flange between the socket and the sleeve, a handle member having an opening to receive the sleeve and resting upon the said flange, a pair of spring pressed dogs carried by the handle to engage with the notches of the flange, and a key member for bringingone of the dogs out of such engagement.

2. In a device for the purpose set forth, a stock which is substantially square in cross section and which is provided with an opening entering from its end, two jaws pivoted within the opening, said jaws hav-V ing their outer faces angular and projected through the opening, the ends of the jaws being notched, the meeting facesof the said jaws being grooved to provide a socket which communicates with the said notch,ra threaded spindle projecting from the stock, a revoluble head upon the spindle, a sleeve having a square bore surrounding the stock and contacting with the projecting edges of the jaws, said sleeve having a collar extension which surrounds the spindle, a nut upon the spindle received in an openingin the collar and projecting through the said opening, the sleeve at the juncture with the collar being formed with an annular flange having peripheral notches, a handle having .an opening to receivethe collar and resting CLARENCE I.
